摘要
提出了面向图形结构单元的变量关联参数化原理与方法 ;给出了图形结构单元类的参数化描述模型 ;基于变量约束的不同图形结构单元的关联方法 ;提出了图形结构单元内的参数化自律约束和不同图形结构单元间的关联约束 ;以变量和关联数据库为驱动源 ,介绍了零件内不同图形结构单元变量关联和驱动求解方法 ,以及存在装配关系的零件间双向关联的参数化求解过程。
A promising approach to variable relation parametric based on the graphic structure modelon has been put forward . The paper gives a parametric description model of graphic structure modelon , and relating method for different graphic structure modelon based on variable constraint . In the same time , with the aim of practicality engineering , the self-discipline constraint in modelon and relating constraint between two modelon are given . Finally , with the tool of variable and relating dbase , We give the solving method of variable relating and variable-driven among different graphic structure modelon in a part , and double-acting variable relating parametric method among different parts in which assembly relation are existed.
